abstract

Charge-spin conversion phenomena such as the spin Hall effect allow for the excitation of magnons in a magnetic layer by passing an electric current in an adjacent nonmagnetic conductor. We demonstrate that this current-induced modification of the magnon density generates an additional nonlinear longitudinal and transverse magnetoresistance for every magnetoresistance that depends on the magnetization. Using harmonic measurements, we evidence that these magnon creation-annihilation magnetoresistances dominate the second harmonic longitudinal and transverse resistance of thin Y$_{3}$Fe$_{5}$O$_{12}$/Pt bilayers. Our results apply to both insulating and metallic magnetic layers, elucidating the dependence of the magnetoresistance on applied current and magnetic field for a broad variety of systems excited by spin currents.

  1. Large enhancement of spin-flip scattering efficiency at Y3Fe5O12/Pt interfaces due to vertical confinement

    cond-mat.mes-hall 2024-12 conditional novelty 6.0 of 10

    Nonlinear SMR in YIG/Pt reveals that interfacial spin-flip scattering is dominated by subthermal magnons, making the spin conductance gs strongly field- and thickness-dependent, with an inferred 30x enhancement at 10 nm YIG.

  2. Alternative harmonic detection approach for quantitative determination of spin and orbital torques

    cond-mat.mtrl-sci 2024-12 conditional novelty 5.0 of 10

    An out-of-plane harmonic Hall measurement geometry quantitatively extracts spin-orbit and orbital torques in in-plane magnetized films and reproduces the two-fold torque enhancement from a Cu/CuOx interface.
